Headlight Modulator
Hi Saftie: Yes, I have one, its on my MY2010, 10090RR. Made by the same company as in the YouTube video, Signal Dynamics.
I installed it 3 years ago, and have since rolled over 10,000 miles on the bike, with zero problems. It is feature rich and simple to engage/disengage without having to add a remote switch.
Signal Dynamics used to make the device as a 'universal fit' now it is only Plug & Play. Simply clip off the molded on plug, or purchase the universal adapter harness. I buried the device on my bike along side the headstock and kept the wiring neat and invisible between the headlight housing and the upper fork 'ears'. Download the installation instructions from Signal Dynamics for a superb wiring diagram.
A also recommend their excellent Back Off brake light modulator. It also is tiny and tucks in near the taillight.
Photo attached show the simple home made bracket to tuck the daylight sensor under the instrument cluster.
Usual disclaimer; simply a 'silly' safety minded customer of Signal Dynamics, no business relationship.
Ciao,
Dick
